我在ubuntu16.04上的python（3.5.2）中使用matlab.engine（MATLAB R2016b），
遵循官方指示"MATLAB API for Python"。
面对这个奇怪的问题，我感到很困惑。
导入matlab.engine后导入matplotlib时效果很好：
import matplotlib
import matlab.engine
eng = matlab.engine.start_matlab()
#...
但是，如果没有先导入matplotlib，则jupyter-notebook中会出现以下错误：

此外，从终端运行.py文件时会显示类似的错误消息：

为什么？
导入matplotlib似乎包含了名为'matlabengineforpython3_5'的缺失模块？这是真的吗？
matplotlib和matlab.engine之间的关系是什么？
有没有更好的方法来解决这个导入问题？
谢谢：）
